Bell Ringer: How is music different from other sounds?

• • Finish 15.1 Notes

  • How to change the sound for musical instruments:

    • Loudness

      • Play harder or softer (create vibrations with larger or smaller amplitudes

    • Pitch

      • Change the length of the vibration (changes wavelength, thereby changing frequency)

      • Change properties of medium (e.g. tension of string) (changes speed, thereby changing frequency)
